Hi, I have a number 2 (10a) fuse constantly blowing. Air bag light is on and it controls blower motor relay, backup lights etc. (2002 ford ranger) I went up to 20a and no further and it still keeps going out. I checked the blower motor and even unplugged it, replaced the blower relay, and none of this helped. It blows when I sometimes step on the brake if it is already driving, but lately I can't get it out of park without the fuse blowing when I operate the gear shifter. Any help?

It sounds like the blower speed controller is shorted to ground here is the blower motor wiring so you can see how the system works and a guide to help check the wiring with fuse locations as well.

I had the blower motor relay go bad which caused the fuse to blow, I hope this helps.
